CHAIR. V

To all whom it may concern.

Be it known that I, FRANCIS O. HALL, of Kansas City, in the county ofJackson, and in the State of Missouri, have invented certain new anduseful Improvements in Chairs, and do hereby declare that the followingis a full, clear, and exact description thereof.

The object of my invention is to provide an article of furniture havingelements enabling its use as a chair or stool whose height may beadjusted, and as a table, and in the form in which I prefer to embody myinvention I use to the extent that it is possible the adjustable chairor stool structure which forms the subject of my Patent No. 1,020,902 ofMarch 19, 1912, and one of the specific objects of my invention is toadapt that structure for use as a part of the table standard or support.

Having in View the general and particular objects stated, my inventionconsists in the article of furniture constructed substantially ashereinafter specified and claimed.

In the accompanying drawings-Figure 1 is a side elevation of an articleof furniture embodying my invention arranged for use as a table; Fig. 2is a vertical section thereof; Fig. 3 is a vertical section at rightangles to Fig. 2, showing the article arranged for use as a stool, whenextended to its full height; Fig. 4 a detail bottom view showing theratchet bar operating mechanism; Fig. 5 a detail view in perspectivefrom the underside showing the table top; and Fig. 6 a detail view inperspective of one of the ratchet bar engaging teeth.

The embodiment of my invention illustrated in the drawings, generallydescribed, comprehends a base'member which is in the form of theordinary stool having a general form of a frustum of a pyramid, andconsisting of a top 10 and four downwardly and outwardly diverging legs11, and a seatcarrying member consisting of a rectangular box-like frame12, and a seat 13 attached to the top of the frame, which seat-carryingmember is capable of vertical movement through an opening in the basetop 10 so that the seat-carrying member may be lowered within the basemember so as to be wholly contained therein, with the top of the seat 13flush with the top 10 of the base so that the general appearance is thatof an ordinary stool which may he sat upon or Specification of LettersPatent.

stood upon, and is in a compact form for convenient transportation orhandling, in all of which respects the structure is similar to that ofmy above mentioned patent as well as in the'particular that at each ofthe four corners of the box-like seat member 12 there is a verticallyextending ratchet bar 15 hung on a pivot 16 at the underside of the seat13. For each of the ratchet bars there is a detent or tooth 17,preferably in the form of a lug on a bracket 18 which is secured to thebase top 10, and which is shown in detail in Fig. 6. The ratchet barsare yieldingly pressed outward so that the teeth thereof will engage thedetent 17 by means of a pair of inverted U-shaped springs 210 that areat tached to opposite sides of the seat-supporting member 12 so thatthey have free ends to bear against the ratchet bars. The ratchet barsare connected together in pairs at their lower end by means of aV-shaped rod or bar 19, (see Fig. 1) the extremities of the legs beingattached to the respective ratchet bars of a pair, and the two V-shapedrods approach each other at their contracted ends and they are connectedtogether by a loop 20 on the lower end of a vertical rod 21 which ashort distance below the seat 13 has a handle forming cross bar 22accessible through a hand hole 23 in the seat 13, so that by passing thefingers of the hand through the hole one may reach the handle 22 andlifting thereon the lower end of the ratchet bars, by reason of theconnection between the rod 21 and the ratchet bars, consisting of theVshaped rods 19, will be drawn inward and disengaged from the supportingdetents so that the seat 13 is free to be lowered if it is in a raisedposition, such as is shown in full lines on the drawings, this operationbeing similar to that of the corresponding structure in my patent abovereferred to. The connection between the operating rod 21 and the ratchetbars operated by the V- shaped rods 19 is different from that of mypatent and is superior thereto in that a stiffer support is aflorded forthe ratchet bars and yet flexibility in the directions in which it isrequired, is provided, no other connection between the ratchet bars of apair at their lower ends being needed than is afforded by the V-shapedrods 19.

The table top attachment consist of two leaves or halves 31 pivotedtogether by a hinge 32, and to the underside of each half or leaf 31 ispivoted a leg 33 by means of a hinge 330 so that the leg may swing froma collapsed position against the underside of the leaf to a verticalposition, as shown in the drawings, the lower ends of the two legs, whenin a vertical position, passing through the hand hole 23 and beingprovided with upper and, lower shoulders 3st to engage the upper andlower sides, respectively, of the stool seat 13, and thereby interlockthe table legs with the seat 13 and support the table at the desiredlevel above the seat 13. The legs 33 may swing toward each othersutliciently to enable their shouldered lower ends to pass into the seathole 23 and whentheyare in proper posi tion therein they are swunsufliciently outward to cause interlocking and supporting engagementbetween their shoulders and the seat 13, and they are locked inseat-engaging position by a cross bar 35 pivoted by a hinge 3G to one ofthe legs which may be swung from a position lying against said leg, toone extending at right angles betweenthe two legs, as shown in Figs. 1and 2 of the drawings, and thereby prevent the accidental orunintentional disconnection of the legs and the seat 13. A stop shoulder37 provided on the leg 33 to which the cross bar 35 is not pivoted tolimit the swinging movement of the cross bar 35 to a posi tion at rightangles to the two open legs 33. The table when applied is securely andrigidly supported, and yet by reason of the hinging of the two leaves 31to each other and the hinge connection between the legs and the leavesand between the cross bar 35 and one of the logs, the entire tablestructure when not in use may be folded into a .very compact state,requiring but little room. To facilitate the insertion of the legs intothe seat hole 23, the lower ends of the legs are beveled, as clearlyshown in Fig. 2.

It will be evident that I provide a structure, which, with a minimum ofparts is capable of use as an adjustable chair or stool and as a table,and when the table top is removed it can be folded compactly so that itrequires little space for its accommodation.

It will be evident that my invention may be embodied in structuresdiffering in form and arrangement of parts from that which I illustratein the drawings, as one embodi' ment of my invention, the table, indeed,being in the nature of an attachment, adapted for use with various otherarticles of furniture, and the scope of my claims is to be determined inthe light of this statement.

Having thus described my invention what I claim is-- v 1. A tableattachment comprising two leaves hinged together, a leg hinged to eachleaf, the legs having support-engaging shoulders, and a locking barpivoted to one of the legs and adapted to engage the other leg.-

2. The combination of a support having a hole in its top, a tablecomposed of two leaves hinged together, two legs pivoted to therespective leaves having at their free endsshoulders to interlock withopposite sides of the hole in the support top, and a cross bar hinged toone leg and adapted to engage the other leg.

In testimony that I claim the foregoing I have hereunto set my hand.
